Hello everyone, I want to invest €1,500 in a new PC, and I ask for your help because I don't have much knowledge of PC computing, as I work with a Mac and use the PC only for gaming, so I get lost in so many details about motherboards, processors, and graphics or memory cards. My home PC has become too small for me, I bought it about 6 years ago and it was assembled for me in a neighborhood store that no longer exists. They made me a custom PC for 2,000 euros and it lasted me those 6 years and would probably last me more, but the latest games are running at 15 frames and honestly, I don't enjoy it and I want to change. What I asked the store was that it wouldn't give me problems, nor would I have to keep changing parts or be constantly looking after it, and they were right, in 6 years not a single problem, not a single format or a single part that broke. So, well, above all, understand that I'm not going to touch it for many years, nor am I going to do overclocking or whatever it's called, that the store you recommend me leaves the inside well for cooling, it's only for gaming like for example guild wars 2 or planetside 2, for work I already have the Mac. What it should be, Intel with nVidia graphics, monitor of 24+ and LG, you also have to include the operating system, I still have XP, but I have no idea if I should buy the new one or the previous one, and if in 32 or 64 bits, and it should come all installed and tested, I have a keyboard and mouse so I don't have to buy it, I don't really care about the sound, as I always use headphones, so anything that sounds good is fine with me. I've been looking at stores with PCs made for 1,200-1,500 € for a few days, but then there are people who say that the I7 is better not to have, that the such and such graphics card is also better not to have, that if the power supply is better less than if the memory and of course, in the end, those of us who don't understand get doubts if it will be a good purchase or something unnecessary. Well, that's all, I really appreciate any help.
